Computational and Statistical Guarantees of the \textit{c}-Rectified flow
Leda Wang, Zhehao Xu, Qiang Liu +1
Recently, rectified flow has emerged as a fundamental framework for large-scale image generation, powering state-of-the-art systems such as FLUX.1 and Stable Diffusion 3. Despite i…
Two-chart Beltrami Optimization for Distortion-Controlled Spherical Bijection with Application to Brain Surface Registration
Zhehao Xu, Lok Ming Lui
Many genus-0 surface mapping tasks such as landmark alignment, feature matching, and image-driven registration, can be reduced (via an initial spherical conformal map) to optimizin…
Free-Boundary Quasiconformal Maps via a Least-squares Operator in Diffeomorphism Optimization
Zhehao Xu, Lok Ming Lui
Free-boundary diffeomorphism optimization, an important and widely occurring task in geometric modeling, computer graphics, and biological imaging, requires simultaneously determin…
From optimal score matching to optimal sampling
Zehao Dou, Subhodh Kotekal, Zhehao Xu +1
The recent, impressive advances in algorithmic generation of high-fidelity image, audio, and video are largely due to great successes in score-based diffusion models. A key impleme…
